This article will introduce the methods and functions of turning off JavaScript from the following aspects.
1. The role of JavaScript script
JavaScript, usually abbreviated as JS, is a high-level programming language. It is widely used in Web front-end development to provide dynamic effects for web pages, such as form validation. , image carousel, dynamic update page, etc. The JavaScript language interpreter can be directly embedded in web pages, and combined with HTML and CSS languages, to achieve web page interaction effects. Advertisers use JavaScript technology to embed advertising scripts into web pages to achieve pop-up ads and other services. Therefore, changing a webpage that runs smoothly on a website to one without JS will have a huge impact on some websites.
2. The significance of turning off JavaScript
Although JavaScript scripts provide a better user experience on web pages under normal circumstances, malicious JavaScript scripts on some websites will continue to capture user private data and push notifications Pop-up ads, etc. This kind of JavaScript script consumes user bandwidth, causing web pages to slow down or even crash. At this time, turning off JavaScript can not only protect user privacy, but also reduce web page loading time and improve the speed of entire web browsing.
3. How to turn off JavaScript in QQ Browser
QQ Browser is a browser based on the Webkit kernel and has perfect support for JavaScript scripts. Enabling or disabling JavaScript is easy, just click on the browser settings and then find the JavaScript switch button in the browsing options bar.
The steps are as follows:
1. Open the QQ browser, click the three vertical dots in the upper right corner, and enter the browser settings.
2. Find the "Browsing Options" column in the settings interface and click the JavaScript button inside to turn the JavaScript function on or off.
3. After turning it on/off, re-enter the corresponding website to experience different web page effects.
It is worth noting that after turning off JavaScript, some website functions may be restricted, so you need to make a choice based on the actual situation.
4. Possible problems after turning off JavaScript
After turning off JavaScript, because the browser no longer interprets the JavaScript script in the web page, some functions of some web pages will be restricted or invalid, such as the picture wheel. broadcast, form submission, etc. In addition, some users are accustomed to turning off JavaScript, resulting in the excellent dynamic effects and information push in the web page being unable to be displayed, affecting the user experience.
5. Summary
JavaScript plays an important role in modern web development, but it has also been abused by malicious elements. When using QQ Browser, you can turn on or off the JavaScript option according to the actual situation to achieve a better web browsing experience. In our daily use, we should also strengthen our awareness of security and not easily click on links in text messages, emails, and social media to avoid personal information being attacked by bad advertisements.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
